I think my tittle is inaccurate.
When a user clicks on a button I need it to do this:
Response.Redirect("Login.aspx?userid=XX");
How can I get the "userid?" from ?userid. so I can show a page. Like doing "?page=3" and show page 3, in the same page or something.
The Button code is: (just if you need it)
protected void LoginButton_Click(object sender, EventArgs e)
{
Response.Redirect("Login.aspx");
}
Thanks a lot! Sorry if I didn't ask it good, and sorry for the bad English.
Use Request.QueryString:
First Page Sends them another page with their user id in the url:
Response.Redirect("AfterLogIn.aspx?userid=23");
You then Read it using the below code:
var g = Request.QueryString["userid"] //this value should be 23 now
You could then use this g variable to do any amount of custom things (Hide panels, show controls, etc.)
You can do something like this
protected void LoginButton_Click(object sender, EventArgs e)
{
var id = // whatever userid
Response.Redirect("Login.aspx?userid="+ id);
}
and in the pageload of Login page
var userid = Request.QueryString["userid"];
ASP.NET State Management will explain further.
Hope this helps
